START_STICKY does not work on Android KitKat

由 我怕爱的太早我们不能终老 提交于 2019-11-26 06:45:36
One of my apps has a backgrouod service that uses the START_STICKY return code from onStartCommand to automatically restart when the system kills it. It seems that this is no longer working on Android KitKat. Is there any solution for this ? Should I be doing something different on Kitkat to keep the service running ? Note: There is a similar discussion on the Android-Devlopers group about swiping the app from the recent apps list behaves. Could this two issues be related ? https://groups.google.com/forum/#!topic/android-developers/H-DSQ4-tiac Edit: Saw that there are open bugs on Android

And what is the role of each? 回答1: onCreate() is called when the Service object is instantiated (ie: when the service is created ). You should do things in this method

由 与世无争的帅哥 提交于 2019-11-26 05:55:35
问题 I am using Service in my application and it needs to run until my application is uninstalled, but the problem is it gets killed by OS. How can we prevent it from being killed by OS? Or if it gets killed can we restart that service again through programmatically? 回答1: You may run the service in the foreground using startForeground(). A foreground service is a service that's considered to be something the user is actively aware of and thus not a candidate for the system to kill when low on
